Re: question for the eastern Sierra guys
Well, I can tell you what I haul, but whether that's the definitive box is another question. Google Mammoth Fly Fishing adventures and get on Harry Blackburn's web page. He has a dandy hatch chart.
coachmen or trudes (brookies love them)
Assorted copper johns
assorted pheasant tails
prince (assorted colors)
midges (zebra, RS2, blood)
Big assortment of buggers
Nothing too exotic in my box, and I do stop in at the shops to get current local stuff. If you're hitting the EW for sure stop at Ken's.
good luck...hope this helps. -Mike
